Virus Total browser extension

Article for: Everyone
Difficulty: Very easy
Importance: Could be occasionally useful

This simple extension allows you to check links to see if they are safe.
Virustotal aggregates many security companies online scanning capabilities. It then checks files or sites using them all. They check with over 70 different companies to determine if a site or a file is dangerous. They make extensions for both Firefox (including Cliqz) and Chrome (including Brave and Vivaldi). These allow you to check:
  • a site you are on, or
  • a link to a site you might visit, or
  • a link to a file before you download it.
To scan a site just click on the icon and select "Scan current site"


To scan link to either a site or a file just right click on the link and choose Check with VirusTotal


Even if you seldom use it, this is a nice tool to have in your browser. The images I've shown are for the Chrome extension (using Vivaldi), and they look a little different in the Firefox / Cliqz extension. But they work the same way.
